Deformation characteristics and formability enhancement during ultrasonic-assisted multi-stage incremental sheet forming

Journal of Materials Research and Technology, 2022
Although the multi-stage incremental sheet forming strategy is beneficial for manufacturing complex geometrical shapes via objective transitional stages, the forming limit and geometric accuracy are highly dependent on intermediate shapes, which need ...

Guideline for Forming Stiffened Panels by Using the Electromagnetic Forces

Metals, 2016
Electromagnetic forming (EMF), as a high-speed forming technology by applying the electromagnetic forces to manufacture sheet or tube metal parts, has many potential advantages, such as contact-free and resistance to buckling and springback.

Robot-Assisted Cold and Warm Incremental Sheet Forming of Aluminum Alloy 6061: A Comparative Study

Metals, 2023
Incremental sheet forming (ISF) requires no or partial dies for sheet metal fabrication and is widely used for small batch production. In this process, necking is either suppressed or delayed due to the localized nature of tool–sheet contact; hence, more

Solidification of Al alloys under electromagnetic pulses and characterization of the 3D microstructures under synchrotron x-ray tomography [PDF]

, 2015
A novel programmable electromagnetic pulse device was developed and used to study the solidification of Al-15 pct Cu and Al-35 pct Cu alloys. The pulsed magnetic fluxes and Lorentz forces generated inside the solidifying melts were simulated using finite

Induction Heating Validation of Dieless Single-Point Incremental Forming of AHSS

Journal of Manufacturing and Materials Processing, 2017
Advanced high-strength steel (AHSS) is subject to a high deformation in geometry due to spring-back and high forces during forming. Therefore, dieless single-point incremental forming supported by induction heating was introduced.

Codonopsis pilosula twines either to the left or to the right [PDF]

, 2012
We report the twining handedness of Codonopsis pilosula, which has either a left- or right-handed helix among different plants, among different tillers within a single plant, and among different branches within a single tiller.

Experimental Evidence on Incremental Formed Polymer Sheets Using a Stair Toolpath Strategy

Journal of Manufacturing and Materials Processing
Incremental sheet forming represents a relatively recent technology, similar to the layered manufacturing principle of the rapid prototype approach; it is very suitable for small series production and guarantees cost-effectiveness because it does not ...

A natural formation scenario for misaligned and short-period eccentric extrasolar planets [PDF]

, 2011
Recent discoveries of strongly misaligned transiting exoplanets pose a challenge to the established planet formation theory which assumes planetary systems to form and evolve in isolation.
